Hi, I'm running Solr 5.3 in one of our applications. Currently, we have one Solr Master and one Solr slave running on AWS EC2 instances. I'm trying to add an additional Solr slave. I'm using an Elastic LoadBalancer (ELB) in front of my Slaves. I see the following error in the logs after adding the second slave,
java version "1.8.0_121" Solr version: 5.3.0 1696229 org.apache.solr.common.SolrException: Core with core name [xxx-xxx-xxxx] does not exist. at org.apache.solr.handler.admin.CoreAdminHandler.handleReloadAction(CoreAdminHandler.java:770) at org.apache.solr.handler.admin.CoreAdminHandler.handleRequestInternal(CoreAdminHandler.java:240) at org.apache.solr.handler.admin.CoreAdminHandler.handleRequestBody(CoreAdminHandler.java:194) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:143) at org.apache.solr.servlet.HttpSolrCall.handleAdminRequest(HttpSolrCall.java:675) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:443) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:210) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:179) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1652) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:585) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:577) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:223) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1127) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:515) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1061) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:215) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:110) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:97) at org.eclipse.jetty.server.Server.handle(Server.java:499) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:310) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:257) at org.eclipse.jetty.io.AbstractConnection$2.run(AbstractConnection.java:540) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:635) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:555) at java.lang.Thread.run(Thread.java:745) Also, when I hit the Solr Admin UI, I'm able to see my core infrequently. I have to refresh the page multiple times to be able to see it. What's the right way to add a slave to my existing setup? FYI - the Solr Replication section in solrconfig.xml is exactly the same for both the Slaves. Thanks, Zafar Khurasani
